Cortelco Desk Phone Conversion – VOIP Ready w/ Grandstream HT801v2 ATA + PoE (All Components Built-In)

This isn’t just a phone — it’s a conversation starter. We’ve taken a genuine Cortelco desk phone and fully converted it for modern VOIP service. All the required hardware, including the Grandstream HT801v2 ATA and PoE injector, has been neatly installed inside the original chassis. The result? A clean, clutter-free setup that keeps the vintage style but works like new.

Features:

• Authentic Cortelco desk phone – classic design, modern performance.

• Grandstream HT801v2 ATA (installed internally) – directly connects to SIP/VoIP providers.

• PoE injector (installed internally) – one Ethernet cable provides both power and data.

• 802.3af/at PoE switch required – ensures proper operation.

• Clean integration – no extra boxes, wires, or adapters hanging off the side.

• Tested & verified – dial, ringer, and handset audio fully functional.

• Other Colors available*

Why this build is unique:

• All-in-one design: modern electronics hidden inside the original Cortelco chassis.

• Professional finish: looks like a stock desk phone, but it’s VoIP-ready.

• Practical + stylish: great for home offices, businesses, or retro tech enthusiasts.

• Plug and play: just connect it to your PoE switch and configure your SIP provider.
